BALANCED PUMP.

SPECIFICATION forming part of Letters Patent No. 301,273, dated July 1 1884.

(No model.)

To all whom it may concern.-

Be it known that I, HAILEY S. RAMSEY, a citizen of the United States, residing at Oo manche, in'the county of Comanche and State of Texas, have invented a new and useful Balanced Pump, of. which the following is a specification.

My invention relates to improvements in balanced pumps having a horizontal cylinder provided with a horizontally reciprocating plunger, and a curved cylinder placed direct- 1y under it, provided with a curved plunger, both having suitable valves operating automatically in conjunction therewith; and the objects of my improvements are, first, to provide a pump by means of which air, water, or other fluids may be conducted or raised with but little propelling power; second, to afford facilities for readily attaching it to be driven by any steam-engine or motive power; and, third, to admit of its quick adjustment to force from the smallest quantity to its full capacity. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical elevation of the machine, partly in section; Fig. 2, a top view of the same.

Similarletters refer to similar parts through out the several views. The horizontal cylinder A (shown attached to post J) has an opening, 13, in cylinder-head O, which is closed by valveD when the plunger E moves toward it. Through this opening the fluid to be conducted enters as the plunger E moves from it. This plunger also has an opening of suitable size through its center, and a valve,F,covering it, which forces the fluid that has passed through the plunger out of cylinder A down through flexible conductor G, and out through hollow and curved plunger H into curvedcylinder I. The valve to, covering the opening 0 in this curved plunger, opens outward automatically, admitting of the free passage of the fluid, but closes when the plunger is moved in an opposite direction, when the fluid that has passed through it is forced through curved cylinder I into reservoir K.

L is a shaft which may be arranged to turn in suitable bearings. To it is secured abandwheel, M, over which a band may pass from an engine or other motive power imparting motion to it. On the end of this shaft is a crank, N, to which is attached one end of a connectingrod, O. The other end is pivoted to rocker-arm'I, that is pivoted to suitable frameworlgR. The end of the rocker-arm forms a -l, to the upper end of which is pivoted a connecting-rod, S, that is attached to piston-rod working in horizontal cylinder. This rod is attached to yokcf, that is secured to plunger E, and by this piston and rocker arm the plunger receives its reciprocating motion. To the lower end of this rocking arm is pivoted aconnecting-rod,V, that is connected to the curved plunger H at W', by which it receives its reciprocating motion.

Y is a weight attached to rocker-arm for the purpose of counterbalancing the pressure it is desired to maintain in reservoir K,which may be regulated by means of said weight being adjustable backward or forward in notches i of the arm 1?.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is a 1,. The combination, in a balanced pump,ot' a horizontal cylinder, A, provided with a yoked plunger, E, with a curved plunger and HALEY S. ltAlvISEY.
